PHP cookie和时间

问题描述：

I'm am experimenting with cookies for the first time and I don't think I'm understanding this or my code is doing something loopy. Someone mind helping me get back on the right path?

I keep re reading the php.net help but i think my mind is mush now :/

$currentTime = strtotime("now");
$popup_exp = strtotime("+1 hour");

if (!isset($_COOKIE['popup_timer'])) : //does cookie exists? if not, make it
    setcookie("popup_timer", $currentTime);
endif;
if( ($popup_exp > $_COOKIE['popup_timer']) ): 
    //show my popup
endif;

我正在尝试第一次使用cookies，我不认为我理解这个或我的代码正在做一些循环的事情。有人介意帮助我回到正确的道路上吗？ p>

我一直在阅读php.net的帮助，但我认为我现在的想法很简单：/ p> $ currentTime = strtotime（“now”）; $ popup_exp = strtotime（“+ 1小时”）; if（！isset（$ _ COOKIE ['popup_timer']））：// cookie存在吗？如果没有，请将其设为 setcookie（“popup_timer”，$ currentTime）; endif; if（（$ popup_exp＆gt; $ _COOKIE ['popup_timer']））： //显示我的popup endif; code> pre> div>

答

Not getting your code quiet well, but as you commented

if(!isset($_COOKIE['popup_timer'])) {
   //Show popup
   setcookie("popup_timer", '', time()+3600);
}

The above will throw a pop up only if the $_COOKIE is not set, once it throws the pop up, a cookie will be set with an expiration set to an hour.

答

You should compare your current time with the time stored in the cookie, like this

$currentTime = strtotime('now');

if (!isset($_COOKIE['popup_timer'])) {
    setcookie('popup_timer', $currentTime);
} else {
    if ($currentTime > $_COOKIE['popup_timer'] + 60 * 60) {
        // If an hour has passed since cookie creation
        // show your popup
    }
}
